The USB Jewel Mobile Watch Flash Drive from Brando is another piece of USB jewelry that I find so fascinating. This silvertone necklace has a watch pendant that hides a USB 2.0 flash drive. The “mobile” in the name comes from the shape of the pendant – it looks a little like a clamshell-shaped mobile phone. The watch has crystal hour markers and your choice of a white, blue, black, or pink face. Inside, there’s a 2, 4 or 8 GB USB flash drive. The USB drive is compatible with Windows 7/Vista/XP, Linux 2.4, and MAC OS X or newer. The USB Jewel Mobile Watch Flash Drives are $22 (2GB), $25 (4GB), or $36 (8GB).
